Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!

Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.

As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.
CIRCUIT OPERATION
1-3) PB MODE
When playing the tape, the signal which is picked up from the tape is amplified 50 dB. Then luminance signal goes to pin 11 and color signal goes to pin 7 through AGC. Luminance signal of pin 11 is input to pin 39 of IC301 through PB EQ circuit in order to match playback characteristic. Color signal which is output from pin 7 of IC401 is input to pin 15 of IC301. PB FM signal is demodulated by IC internal demodulator then it is input to pin 3 after MAIN DE-Emphasis process. If this output signal has burst, color component will be separated by X303. If it has burst, it is input to pin 4 of IC301 through Yemphasis circuit. The signal which is input to pin 4 is output from pin 12 through 3.5M LPF, then it is input to pin 10 through 1H CCD. Color signal which is input to pin 15 passes ACC in order to stabilize level, then 3.58H components will be extracted by 3.58M BPF through Main Converter. This 3.58M color signal is input to pin 25 of IC301 in order to eliminate crosstalk, then it will be mixed with luminance signal after passing CNR circuit. Finally Y/C composite video signal is output from pin 34.
